I am a fairly savy computer guy but things change so fast now days. I have Windows Vista Ultimate (disaster) on my computer. I only have an 80 GB hard drive which is nearly full. I purchased a new 320 GB hard drive and installed it. The BIOS sees it and indicates it is good and so does the OS Device Manager. Device Manager diagnostics say it us working properly. I click on computer and no new drive. It almost has to be some sort of setting I do not know about. I have been reading of others having this problem and it seems the only thing that has ever corrected it was to format and totally rebuild your software. Any ideas?
